Time-value series for simulation data


simscape.logging.Series represents simulation data for a variable in a model. The series is a representation containing time-value pairs for each simulation step. The size of the series is determined by the number of simulation steps. You can also limit the size by specifying the maximum number of logged steps when you set your data logging preferences.

Final nodes in the data logging tree correspond to all the variables logged for the model. Final nodes do not have children nodes, and contain the series data logged during simulation. To specify a Series object, start with a full identifier path from the workspace log variable name to the name of the variable node associated with the series, and conclude with .series. For example, simlog.Translational_Spring.v.series is the series containing the simulation data for the variable v (velocity) of a Translational Spring block at the top level of a block diagram, given the default workspace variable name, simlog.


This object is created automatically during simulation, as part of the simulation log workspace variable, if you enable data logging for the model.
